Abstract (en)

[origin: EP0808659A2] A sand cleaning plant whose principal component is an upstream separator (10). This separator is a tank (20) with a double bottom (22, 23) into which water is passed so that it rises out of holes in the upper plate (22) to form a fluidised bed with the sand, which is then separated into light and heavy layers. The light fractions are withdrawn at a relatively higher level than the heavy fractions, which are removed by a screw conveyor (25). The separator is fed by screw conveyor (9), at the opposite side to conveyor (25). Material is moved along the bottom (22) to conveyor (25) by reciprocating bars (31), working at two levels. Tank (20) is to have a rectangular cross-section with the double bottom in a horizontal plane.
